Sun Java System Communications Services software provides robust security measures to protect the integrity of your data and the privacy of customers, partners, and employees. Sun Java System Communications Services supports Secure Sockets Layer (SSL) and Transport Layer Security (TLS) encryption to protect information assets. In addition, a messaging proxy can provide an additional layer of security at the firewall to further protect sensitive information. Extensive antispam and virus protection features also help protect the IT infrastructure and prevent lost productivity due to spam distraction or virus disruption.
Sun Java System Messaging Server supports the Mail Abuse Protection System (MAPS) Real-time Black Hole List to prevent email from known spammers, address verification to help ensure that messages are sent from valid domains, and relay blocking to prevent use of the server as a spam relay. Support for server-side rules enables system administrators and end users to configure filters on the server (before a message arrives on the desktop) to remove suspected spam, viruses, or other inappropriate content. Sun Java System Messaging Server has been preintegrated with Symantec Brightmail anti-spam filtering technology and SpamAssassin, an open source spam filtering software package. A conversion channel facilitates integration with other third-party, content-filtering software for richer spam and virus protection. In addition, a throttling mechanism helps prevent denial-of-service attacks.
In contrast to Sun, Microsoft products, including Microsoft Exchange, have consistently been plagued with notable security weaknesses. The distributed nature of the Microsoft Exchange solution means that multiple copies of files are stored on numerous servers, making it difficult to implement robust security measures. In the event of a virus attack, IT administrators literally have to shut down, clean up, and often, install security patches on each Microsoft Exchange server, one at a time. This process is slow, labor-intensive, and costly, especially when dealing with dozens or hundreds of servers. The bottom-line impact is higher IT labor costs and decreased worker productivity due to system downtime
